In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning. Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "Navigate to the Applications folder, and then go into the Utilities folder."
A block of code is set as follows:
evens = []
with open as f:
for line in f.readlines():
evens.append(line.split()[1])
Any command-line input or output is written as follows:
sudo apt update
sudo apt install Python3 build-essential
New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Select Markdown from the drop-down list on the toolbar."
Warnings or important notes appear like this.
Tips and tricks appear like this.
